Filed July 6, 1959, Ser. No. 825,129 6 Claims. (Cl. 20-55) My invention relates to storm sash assemblies for installation within window or door casings or the like of buildings and more particularly to means for securing the storm sashes anchored to their adjacent frames against beilying.

Heretofore, considerable difficulty'has been experienced in maintaining storm sashes, especially relatively long windows and doors, properly sea-led and weather insulated within the so-called double or triple track type of storm sash tirames for the reason that, while each storm sash is supported against outward movement throughout its length by a flange of the frame engaging its outer face,

.the inner iiace of the sash is not similarly supported because it is maintained Within its frame only by means of pins which project from the ends of the sides of the sash into side channels of the frame, thus enabling wind pressure to belly or bulge the sash between its ends, where there are no pins, and create a loose fit between the sash and frame for the admittance of draft and weather and which bellying otten results in breakage of the sash, it being understood that the pins are arranged at the ends of the sash in order that a pair of the pins may be retracted .to permit pivoting of the sash into the building and tilting thereof to dispose the other pins out of the channels.

My invention overcomes the foregoing difiiculties, disadvantages, and undesirable features inherent in the prior art, especially in relatively long windows and doors, it being one of the objects thereof to provide a sash equipped with anti-:bellying 'means operable for anchoring the sash to the Window ira-me against bellying and thereby maintain a weather seal and tight fit.

Another object of my invention is to provide antibellyi-ng means of the foregoing described character which may be applied to sashes already in use without substantial modificationthereof.

An important object of my invention is to provide antibellying means of the foregoing described character which is simple in construction, durable in use, efiicient in operation, and economical in manufacture.

FIGURE 5 is a fragmentary end elevation of one of the sides of the sash.

In teaching my invention, as illustrated in the drawing, ,I employ a window casing 7 of a building .8 or the like and mount Within said casing, in fixed relation therewith,

the framing 9 of a storm sash assembly 10, the latter being of a suitable metal, for instance, extruded aluminum, and equipped with vertical slida-ble sashes S constituting a weather-guard. In the present disclosure, the assembly is of the so-called triple track type with the screen unit being removed in the interest of clarity, it being understood that the double track type may be employed if the screen unit or sash is to be seasonably removed. As viewed in FEGURE l of the drawing, the framing 9 has its interior or lee side disposed inwardly of the building while its exterior or weather side is disposed outwardly of the building. The weather-guard or sashes S are each provided with laterally projecting pins 11 at their upper and lower ends with a pair of the pins being retractable against spring tension. Each sash is also provided with a glass pane 12 secured within a frame 13 which includes channel-like side members 14 having slots 15.

Each of the side members 14 are defined by inner and outer walls 16 and 17, respectively, structurally integrally connected together, at coincident ends, by a side wall 18,

p the opposite end of the outer wall 17 being provided with a kerf 19 on its inner face in which an adjacent portion of the pane 12 is disposed and secured in sealed relation therewith. The opposite end of the inner wall 16 is formed with an inwardly disposed and lengthwise extending projection 20 disposed within a groove. formed in a glazing spline 21 having fingers 22 disposed in compressed relation with the pane 12 for securing the pane fixed within the kerf. The inner wall 16, adjacent the wall 18, is termed with an inwardly offset portion 23 and constitutes a seat for a purpose hereinafter described.

Opposite the portion 23 the outer Wall 17 of each member 14 is formed on its outer face with a dovetail groove 24- in which is mounted a sealing gasket 25 of suitable I .m-aterial, for instance, wool pile, and on its inner face with a rib 26, the gasket and rib extending throughout the length of each wall 17.

- The tfiraming of the assembly 10 is fashioned with a ternary of side rails 27 adjacent each side of thecasing land withthe rails being arranged in a stepped relation Wherein the width between the innermost rails is progressively greater with respect to the outermostand intermediate rails to permit removal of the sash and screen unit in- Wardly within the building as is the usual practice.

Each rail 27 is formed with a channel 28 defined by front and rear walls 29 and 36 respectively, connected together by an end wall 31, the wall 29 being provided on its inner face, remote from the wall 31, with a lengthwise extending rib 32. As illustrated in FIGURES 2 and 3 of the drawing, the rear wall 3% is provided with an extension '33 constituting a component of the respective side rail and serving as a stop for receiving thereagainst the gasket 25 to effect a seal between the sash and framing. When the sashes are disposed within the iraming, the pins 11' extend into the channels 15 and engage the walls 29 to maintain the sashes assembled within the framing against displacement into the building and in a manner permitting sliding movement of the sashes within the confines of the rails. Each of thesashes is removed from within the building by operating the aforementioned .retractable pins to their retracted positions, pivoting one end of the sash outwardly into the building and tilting the sash sufficiently to dispose the pins, at the other .end of the sash, out of the channels and the sash out from between the rails. A reverse operation effects assembly of the sashes within the framing. Inasmuch as the foregoing described assembly is of an ordinary construction and does not constitute the invention per se, a more detailed disclosure of the assembly is not deemed necessary.

When the sashes are assembled between their respective side rails, it will be noticed that a relatively large disu tance exists between the top and bottom pairs of pins of each sash and while each wall St) or its extension 33 functions to preclude outward displacement of the sashes from pressure within the building, the only means for precluding displacement of the sashes inwardly into the building, by pressure from without the building, are the pins. In many installations, due to relatively strong winds and the like, the sashes tend to belly or bulge inwardly between their upper and lower ends with the result that the gaskets 25 are rendered inoperative in zones between the ends of the sashes thus permitting a draft into the building from without. In some instances, the degree of bellying is such that the panes are often broken. This condition is especially prevalent in instances of relatively long door and window sashes.

In order to preclude the aforementioned bellying of the sashes, I provide each of said sashes with at least a pair of anchoring devices 39 mounted on the sash. Each device comprises a one-piece elongated body or bar as formed at one end with a right-angularly disposed fingerpiece 41 and at the opposite end with an oifset and parallel extending arm 42 as clearly illustrated in the drawing. Each device has its body 4% disposed in adpressed relation with the pane l2 and extending between the pane and the spline 21, the latter being suitably fitted about the device to permit sliding of the device. In installing each of the devices 39 I form the Wall 18, adjacent the device, with an elongated slot 43 through which the arm 42 operates. The slot 43 is formed by a suitable tool, for instance, a cope chisel, and in a manner wherein a cutout section is turned inwardly to provide a lip or seat 44 for accommodating the arm 42 and serving to limit the inward movement of the device by engagement with the offset portion 45 of the arm as illustrated in FiGURE 2 of the drawing.

In use, the sashes being equipped with the devices 39 and disposed within the confines of their respective side rails, each device is moved by the finger piece 41 towards the adjacent Wall 31 and into the channel 28 and thus rides over the rib 32. When the devices are thus disposed in their extended positions, they serve to anchor the sashes to the framing and preclude bellying of the sashes between their ends by pressure from without the building. The devices may be moved to retracted positions to dispose the fingers 42 out of the channels 28 and thus permit the sashes to be removed from the framing in the ordinary manner.

From the foregoing, it Will be apparent that my invention provides a simple, economical, and efiicient means for preventing bellying or bulging of window sashes especially those of relatively long lengths and is equally useful for overcoming the same diificulties when applied to the panels of doors or the like. It is to be noted that the spline 21 is constructed of a suitable resilient matetrial and, therefore, serves to maintain the body 40 in an adjusted position against the pane to prevent movement by vibration or the like, the spline also serving to engage the portion 45 to limit the retracting movement of the body 40. It will also be noted, as clearly disclosed in FIGURES 2 and 3, that while each of the fingerpieces 41 extends outwardly from the pane 12 of a respective sash, it is relatively short and terminates within the confines of the adjacent spline 21 to preclude engagement with the meeting rail of the other sash during raising and lowering of the sashes relative to each other.

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined solely to the use herein disclosed in connection therewith as it may be utilized for any purpose to which it is adaptable.
